MOP.

To all 'whom it may concern.'

Be it known that we, GUsrAv B. `W1orr MANN and Davis RICH, citizens ofthe United States of America, residing at the city otl St. Louis, in theState ot Missouri, have invented certain new and useful Improvements inMops, ot which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

Our invention relates to mops for scrubbing floors and it has tor itsobject the production of a mop ot this description provided with a clamphead whereby the swab ot the mop may be detachably held to the mophandle and rendered rounding in shape to correspond to the mostprevalent type ot mops and in which the swabs are tied to the mophandle.

By our improvement new swabs may be substituted for the original swabsfrom time to time with readiness and ease and by a simple operation.

Figure I is an elevation ot our improved mop. Fig. II is an enlargedelevation of the mop head. Fig. III is a longitudinal section throughthe mop head. Fig. IV is an end view of the mop head. Fig. V is a crosssection taken on the line VV ot Fig. III. Fig. VI is a perspective viewot the draw nut operable on the terrule of the mop head.

In the accompanying drawings :-A. designates the handle ot our mop and Bthe swab which preferably consists ot cords such as are commonly used inround mops, but

may consist of a cloth or strips of any suitable material.

l designates the ferrule of the mop head that is litted to the handle Aand secured thereto by any suitable means such as screws la. The terruleis provided with a screw thread 2 and terminates at its outer end in abell shaped member 3 that extends beyond the end ot the mop handle andat the interior of which are longitudinal grooves 4, (see Figs. III andIV.) In the body of the ferrule and extending in alinement with thegrooves 4 are longitudinal slots 5.

6 designates a draw loop that is operable in the grooves t and slots 5and the closed end of which is adapted to project beyond the bell shapedmember of the mop head errule to receive the swab B which is passedtherethrough while the draw loop is in an extended position to permitthe ready insertion of the swab through the loop.

draw loop is provided at its inner ends with outwardly projecting arms 7which extend laterally through the slots 5 in the errule 1.

S is a carrier ring loosely fitted to the terrule l so that it may bemoved longitudinally on said ierrule and which is provided withperforated ears 9 through which the arms 7 ot the draw loop may bepassed after they have been extended across the body of the ring at itsupper edge, the ends ot the arms being preferably bent upwardly inengagement with the outer edges of said ears subsequent to the passageot the arms through the ears.

10 is a draw nut fitted to the terrule l and preferably provided withwings ll by which it may be readily turned upon said ferrule. This drawnut is adapted to operate against the carrier ring 8 for the" purpose ofimparting outward movement to said ring and the draw loop fittedthereto.

In the practical use ot our mop, the mop swab is introduced into thedraw loop 6 when the draw loop is in an extended position to whichposition it is readily moved by drawing it outwardly subsequent torotating the draw nut l0 upon the terrule to move it toward the outer orlower end of the mop head. Then when the swab has been introduced intothe draw loop 6 said draw loop is moved inwardly or upwardly to carrythe top portion ot the swab to the bell shaped member 3 of the mop headterrule, a movement that is readily accomplished either by a pull uponthe carrier ring 8 or by the rotation ot the draw nut l0 upon theferrule to move it in an outward or upward direction. After the swab hasbeen brought to the bell shaped member of the terrule it is drawntightly thereto by rotation of the draw nut l0, with the result ofcausing said draw nut to impart outward or upward movement to thecarrier ring and draw loop whereby the swab is spread outwardly due toits engagement with the bell shaped member at the end of the mop headterrule.

The only action necessary in substituting a new swab for one previouslyin use is that of rotating the draw nut 10 upon the mop head `ferrule tomove it outwardly or downwardly thereon, and permit the draw loop to beextended in order that the old swab may be withdrawn from the loop and anew one inserted thereinto, after which the new swab is secured in themop head by the operation of the parts as previously explained.
